Another 'empty chair' moment at the White House?

Protocol is being scrutinised as François Hollande prepares to dine at the White House this Tuesday. One American media usefully informs us that there is "unlikely to be an empty chair" next to François Hollande, this after the recent disappearance of the role of French First Lady following Hollande's separation from Valérie Trierweiler. Elsewhere, what's the wine list? Are the wines French? And what has become of the Obama / Beyoncé rumour?
